Plants Flashcards
Plant Cell:
- General features (3)
- unique features (3)
- eukaryotic, multicellular, autotrophic
- plastids, cell wall, single large central vacuole
Function of Plastids and its 3 types
STORAGE
1. Leucoplasts (colorless storage for starches, lipids, and proteins)
2. Chromoplast (pigment: yellow, red, orange)
3. Chloroplast (chlorophyll for green colour + photosynthesis)
what do you call the membrane around the large central vacuole
tonoplast
what are the 4 only plant parts that can be seen under microscope
nucleus
cell wall
plastids
central vacuole
composition of cell wall of the ff
- plants
- fungi
- bacteria
- cellulose
- chitin
- peptid
2 types of plant tissues
meristematic (immature @ root tips and apical buds)
permanent (differentiated)
3 types of permanent tissues
dermal
ground
vascular
2 types of dermal
E
- shape
- waxy substance that surrounds
- most unique structure where gas exchange happens
- what controls the swelling and shrinking of above ^
P
- where located
- shape
- arrangement
- lacks what at maturity
- composition of walls
- polyhedral
- cutin
- stomates
- guard cells
- corky outer bark
- tubular
- compacted
- protoplasts (entire cell except cell wall)
- suberin
3 types of ground tissues
thin-walled living tissues
Parenchyma
3 types of ground tissues
found in unspecialized regions
Parenchyma
3 types of ground tissues
generally contain the central vacuole
Parenchyma
where are parenchyma cells found?
soft parts like roots and shoots
3 types of ground tissues
called _______cells if contains chloroplasts
Parenchyma
Chlorenchyma
shape of parenchyma cells?
isodiametric and elongated
3 types of ground tissues
has unevenly thickened primary walls
collenchyma
what materials (2) thickens the walls of collenchyma?
and which of which gives it its elasticity
pectin and cellulose
pectin
3 types of ground tissues
acts as main supporting tissue in herbaceous plants
collenchyma
3 types of ground tissues
very thick primary walls and less flexible
sclerenchyma
what is the secondary wall found in sclerenchyma cells
lignin
2 types of sclerenchyma cells and differences in terms of shape?
sclereids - polyhedral to elongated
fibers - long, narrow
movement in hydrilla leaf
cyclosis/cytoplasmic streaming
2 parts of xylem and phloem
xylem: tracheids and vessels
phloem: sieve plates and sieve tubes
DICOT VS MONOCOT (root)
- root system
- organization
- parts (5 & 6)
- Monocot: Fibrous Root
Dicot: Tap Root - Monocot: Organized na paikot xylem
Dicot: xylem gitna with cross-like structure; phloem surrounds
- epidermis
- endodermis
- cortex (labas ng endodermis)
- xylem
- phloem
- pith (wala sa dicot)
DICOT VS MONOCOT (STEM)
- organization
- parts (tig 5)
DICOT
- organized
- endodermis
- cortex
- pith
- xylem
- phloem
epidermis
MONOCOT
- epidermis
- vascular bundles
- xylem
- phloem
- ground tissue
DICOT VS MONOCOT (LEAF)
- midrib?
- # of layers?
DICOT
- w midrib
- 2 layers mesophyll (palisade & spongy)
MONOCOT
- no midrib
- 1 layer mesophyll
